ell whom it may concern:

Be it known that I, Josurrr BARON a citizenof the United States;residing at Rocka- 7 way Beach, in the county of Queens and State ofNewYork, have invented certain new and useful: Improvements inWindow-Cleaning Meehi nes; ofwhich the following is a specificctio'n;This invention relatesto window cleanmg machines, and more particularlyto that type of machines by which the outside sur- "lfaceof window panesare cleaned or washed 1 by the operator standing inside of the buildtoprovide a machine which will-use a mini.

One of the main objects of the invention is to provide a simple'andefli'cient machine of the Character stated. A further object is mum ofwater or other washing liquid during its 0 eration. A still furtherobject is. to p'rovi e a machine having a squeegee or pane engagingmember in combinationwith a. spraying device, these two members be in'gso related that the elndow is washed 25 during one operation of thesqueegee, and dried during the second operation of the squeegee. Furtherobjects will appear from the following detailed description.

In the drawings Figure 1 is a side View of the invention as 'Fi sis asection on line e 2 of Fig. 1, -;Fig. 3 is a section on line H of Fig.1, inig; ,4 is a. section on line 4-4 of Fig. 1,

, vertically slidable squeegee, a spraying deits inner end with lateralarms 2 for bracing and steedying urposes, and near its outer end withsimi or arms 3. 'A suitable tower is mounted upon this base intermediateits ends; This tower is of U-shepe having an inner leg 1. and an outerleg 5, both.

fixedly secured to' the base. The outer leg is of channel constructionand slidably receives the outer sun (i of an'adjusteble U- head 7, theinner arm 7 of which is reduced as at 7 and fits into-a socket-1n theupper Specification of Letters latent. Application and June 10, 1910.Serial x0, mama.

A binding screw 9 1s threuded't irough the bar 10 of theclasp 8 so as to eng age the leg 5 of the tower so as to secure the head7 in vertical adjustment.

The wheel 23 carries an. eccentric pin 28' which is com ccted by a link29 to the lower end of the vertical. arm of an angle rod 30.v The lowerenl of this urm is provided with a short sockel 31 secured thereon by a;bind: ing screw 32, the lower end of which is $101;- ted to receive theupper end of link 29.

The pump barrel 37is-mounted o 1 and secured to a cylindrical housing 39 se :uredto thebottom of tank 38 and provided with a, plurality of apertures 40eommunic iting with the interior of tho tank.
